权利要求：

CLAIMS 1 . An inlet for a vacuum hose, comprising an irregularly shaped intake opening defined by an undulating perimeter. 2. The inlet of Claim 1 , where the perimeter undulates in a direction parallel to a direction that air is to flow through the inlet. 3. The inlet of Claim 2, where the undulating perimeter includes a beveled edge sloping back away the intake opening. 4. The inlet of Claim 3, comprising a screen across the opening to block smaller objects from being sucked through the intake opening. 5. The inlet of Claim 4, comprising multiple channels across the beveled edge of the perimeter. 6. The inlet of Claim 5, where the screen is positioned inside the intake opening behind the most forward parts of the beveled edge of the perimeter. 7. The inlet of Claim 6, comprising: a collar surrounding a discharge opening opposite the intake opening, the collar to connect to a vacuum hose; multiple pockets in the collar; and a magnet in each pocket. 8. An inlet for a vacuum hose, comprising a tapered shell in which an opening into a narrower end of the shell is defined by a perimeter that undulates in a direction parallel to a direction that air is to flow through the shell. 9. The inlet of Claim 8, where the narrower end of the shell includes a beveled edge surrounding the opening. 10. The inlet of Claim 8, comprising a screen across the opening to block smaller objects from being sucked through the opening. 1 1 . The inlet of Claim 8, where the tapered shell comprises a bullet shaped shell. 12. The inlet of Claim 8, comprising a channel extending laterally across the perimeter of the opening. 13. An inlet for a vacuum hose, comprising a shell that tapers from an upstream end to a downstream end that is broader than the upstream end, the upstream end of the shell having an edge thereon that defines an opening and where the edge does not lie in any single plane. 14. The inlet of Claim 13, where: the edge undulates in a direction parallel to a direction air is to flow through the shell from the upstream end to the downstream end; and the edge is beveled so that the edge slopes back away the opening. 15. The inlet of Claim 14, comprising multiple magnets in the downstream end of the shell to adhere to magnets in an upstream end of a vacuum hose.
